Abstract

Embodiments include systems and methods for authorizing software code to be executed or access capabilities in secure operating environments. Profiles may be issued by trusted entities to extend trust to other entities to allow those other entities to provide or control execution of applications in a secure operating environment such as on particular computing devices. A request in a first program may be received from a second program. A profile is then identified. The profile includes at least one entitlement associated with the second program. The profile is authenticated based on a first digest indicative of the profile and the second program is authenticated based on a second digest indicative of the second program. The request is then executed based on the entitlement.

Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application claims the benefit of U.S. Provisional Patent Application No. 61/033,748, filed on Mar. 4, 2008, which is hereby incorporated by reference in its entirety.
  • BACKGROUND
  • 1. Field
  • This application relates to controlling execution of software code.
  • 2. Description of the Related Technology
  • Computing devices may be configured to require that code executed on the computer system be authorized by a trusted party. For example, such authorization may be used to help ensure that the integrity of the computing device is not compromised by malicious or unauthorized code. In some cases, computing devices may be configured to require that code be digitally signed by the trusted party and verified in order to be executed on the computing device and/or to control execution of software that accesses particular resources or services of the device. Verification of the digital signature helps to ensure that the underlying application code has not been modified since it was digitally signed by the trusted authority. However, this security scheme can be difficult to extend to multiple parties that wish to access or modify applications running on the device

  • DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
  • In a computing device in which device applications are cryptographically signed by a first trusted party, a developer profile may be provided that provisions operation of the device to extend trust to applications signed by a second party for a specified list of devices identified by device identifiers. A particular profile may enable applications to run on a device from multiple developers, run on multiple devices, and specify different available capabilities for different devices/profiles/developers. Control of application execution is maintained in a trusted space of a processor of the device. For example, the trusted space may comprise a privileged or supervisor mode or memory space of the processor such as a operating system kernel.
  • A policy service (process) running in untrusted space is configured to manage profiles and determine whether a particular application is executable and identify trusted applications to the trusted space. The untrusted space may comprise a memory space of a user-mode or unprivileged process executing on the processor. cryptographic functions and their accompanying complex calculations may be performed by the user space service. In addition, the user space service may be configured to authenticate software based on one or more profiles and policies that may be specific to a particular developer profile, a particular device identifier, a particular carrier, etc.
  • The policy service may further extend the trust provided to it to provide other applications or services on the device with entitlement data. For example, a first application or library may receive a request for data or a service from a second application. First application requests data indicative of the entitlements of the second application. Based on the data first application responds to, or rejects, the request of the second application.
  • In order to illustrate embodiments of the present invention, FIGS. 1-9 will now be presented below. FIG. 1 illustrates an overall system diagram in, which embodiments may be implemented. FIGS. 2-3 show embodiments of software components and exemplary profile for controlling execution of software. FIG. 4 shows one example of a data flow between software components. FIGS. 5-6 illustrate process flowcharts for executing software based on profiles. FIG. 7 illustrates the interaction of programs on the device. FIG. 8 is another flowchart for authenticating entitlements, for a first program executing on the device. And, FIG. 9 is provided to illustrate one example of a computing device. These figures will now be further described below beginning with reference to FIG. 1.
  • FIG. 1 is one example of a computing environment, which allows for the distribution of authorized software code to computing devices, which are configured to execute only authorized code. Computing devices 100 may be any number of different types of computing devices, including mobile communication devices, desktop computers, laptop computers, handheld computers, personal digital assistant (PDA) devices, mobile telephone devices, media play device, and the like. The computing devices 100 may be configured to require that any code executed on computing device 100 be authorized by trusted authority 102. In other embodiments, more complex authorization schemes may be used, for example, unauthorized software may be executable but only for limited purposes or to access limited device resources while authorized software may be provided more extensive access to resources of device 100.
  • As will be discussed in more detail below, authorization functionality may be provided by, or in conjunction with, an operating system of device 100, which determines whether the code has been authorized by a trusted authority. If the code is authorized and verified as such, it may be generally executed without any further system or user interaction; if the code is not authorized, its ability to be executed on computing device 100 may be restricted or even prevented. In some embodiments, the computing device may alert the user that the code is not authorized and ask the user if they still wish to execute the unauthorized code. In other embodiments, computing devices 100 may be configured to prevent unauthorized code from being executed at all, regardless of the user's wishes.
  • In some embodiments, trusted authority 102 may authorize software 106 by digitally signing software 106. As is known in the art, a digital signature uses public key cryptography to ensure the integrity of data. For example, software developer 104 may provide trusted authority 102 with compiled object code. Trusted authority 102 may then create a digital signature with its private key to the object code of software 106 and may make the code available to computing devices 100.
  • When a request to execute the software may be made on computing device 100, computing device 100 checks the digital signature of software 106 to verify its authenticity and/or authorization. If the software is verified as being signed by trusted authority 102, software 106 may be executed on computing device 100. There are various ways for computing device 100 to check the digital signature of software 106 prior to execution.
  • Software developer 104 may be any person or organization that writes, develops, tests, markets, sells, and/or distributes software to run on computing devices 100. In one embodiment, developer 104 may be a company or enterprise developing software for use on devices 100 that it controls or manages.
  • As part of the software development cycle, software developer 104 may wish to test its software on computing devices that are similar to those on, which software 106 will be deployed in the field. Accordingly, software developer 104 may have one or more developer computing devices 100, which allow the software developer to develop, test, and/or otherwise further the development of software 106.
  • Developer computing device 100 may be the same as the computing devices 100 for, which developed software 106 may be intended. For example, if a software developer 104 may be writing software 106 to be run on a mobile telephone platform such as the iPhone, for example, developer computing device 100 may be an iPhone. Similarly, if the computing device platform 100 targeted for software 106 may be a media player, such as the iPod Touch, then developer computing device 100 may be an iPod touch. By using similar devices for testing and development, software developer 104 may be able to more efficiently develop and test software prior to distributing the software to end user for use on computing devices 100.
  • During the software development process, the code in a software application may be changed frequently. Accordingly, as will be described below, software developer may obtain and use developer access on one or more of computing devices 100. This developer access profile may be installed on the developer computing devices 100, which allows the developer to modify, recompile, and test their software on the devices 100 without the need to request additional code signing services from trusted authority 102.
  • In some embodiments, developer computing devices 100 may also, in addition to receiving developer access profiles, include development and test related software such as a debugging, tracing, or profiling software as part of a standard distribution installed on developer computing devices 100, as part of a pre-provisioning process, or at any other time. In some embodiments, developer computing devices 100 are pre-provisioned with such additional development related software. In other embodiments, development related software may be installed on the device with, or in conjunction with, the developer access profile.
  • FIG. 2 is a block diagram providing one example of how developer computing device 100 may be configured to utilize developer access profiles 208 to execute software modules 206 not signed by trusted authority 102. As noted above, developer computer device 100 may be same type of device as the computing devices 100 for, which software 106 created by software developer 104 may be provided.
  • Software 106 may include one or more software modules 206 stored on, or accessible by, device 100. In one embodiment, storage 209 of computing device 100 can include a computer-readable storage medium (volatile and/or non-volatile) that may be configured to store one or both of software modules 206 and profiles 208. Storage 209 may also be configured to store code of operating system 202, and may further include general purpose storage for device 100. The software modules 206 may be stored temporarily in device 100 or permanently in device 100.
  • Developer computing device 100 may include an operating system. The operating system may be a well-known operating system, such as MacOS, Windows, Linux, Unix, Symbian, or the like. As discussed briefly above, a portion of the operation system, e.g., the kernel of operating system 202 may be configured to require that code executed on device 100 be authorized prior allowing it to be executed on the device. This authorization may take the form of trusted authority 102 digitally signing some or all of the software modules 206. In some embodiments, trusted authority 102 utilizes a code signing certificate, which may be used to verify the source and integrity of the signed computer code.
  • Kernel space of memory used by operating system 202 conceptually may be considered a trusted space. The trust may be established by boot-time authentication of the kernel. In one embodiment, computing device 100 can include hardware support for providing the boot-time authentication of the kernel space used by operating system 202 and its contents. For example, in one embodiment, the boot loader of computing device 100 may authenticate a signature of the kernel software prior to loading and booting the kernel using, for example, suitable public key signature verification.
  • A digital signature may include a digest that may be created, for example, by performing a hash function on the software in order to create a message digest. In some embodiments, incremental code signing may be used. The hash value may be a hash value generated for all or a particular portion of the software. For example, in some embodiments, the software is divided into one or more units such as one or more pages. A hash value is generated for each unit or page of the software. The digest for the software in such embodiments includes a hash value that is generated for an array or table of the hash values of each code or page. The message digest may be then encrypted using a private encryption key associated with trusted authority 102. In one embodiment, the well known SHA-1 function may be used to generate the message digest. The encrypted message digest (also referred to as the signature) may be then appended to the one or more of the software modules 206.
  • In some embodiments, when a request is made on the device to execute software code, operating system 202 may process the request by verifying the source and integrity of the software code by validating the digital signature. If the source of the code is trusted authority 102, and the integrity of the code has not been compromised, operating system 202 may allow the code to run on computing device 100.
  • Developer computing device 100 may also include a device identifier 204. The device identifier 204 may take various forms. In one embodiment, device identifier 204 may be a serial number that uniquely identifies developer computing device 100. In other embodiments, device identifier 204 may be a unique identifier generated by operating system 202.
  • As noted above, developer computing device 100 may also have a developer access profile 208, created by trusted authority 102. Developer access profile 208 may include a set of data that indicates that certain devices are permitted to execute software not signed by trusted authority 102. In one embodiment, a developer access profile 208 allows software developers 104 to modify and recompile source code for their software modules 206, and then test the software modules 206 on developer computing device 100 without needing to request additional code signing services from trusted authority 102. Instead, software developer 104 may be permitted to digitally sign their software modules 206 and run the software on those developer computing devices 100, which have developer access profiles 208 that specify that code signed by developer 104 may be executed on device 100. In some embodiments, the developer access profile may also specify certain operations that developer 104 may perform in testing the software modules 206. For example, a developer access profile 208 may specify that the software modules 206 digitally signed by developer 104 may be debugged on the developer computing devices 100. Developer computing device 100 may also have more than one developer access profile 208.
  • In some embodiments, developer access profile 208 may operate in conjunction with policy service 210. Policy service 210 may take the form of a daemon or other process running in a user (untrusted) memory space of the operating system. Policy service 210 may be further configured to enforce policies specified in the developer access profile 208. For example, if a developer access profile 208 specifies that a developer can trace the operation of the software on the development device, but does not allow debugging, policy service 210 will allow trace operations, but disallow running applications in debug mode.
  • Policy service 210 may be initially started by operating system 202, which may verify a cryptographically secured digest of the service 210 before loading the service. Operating system 202 may maintain a reference to the service 210 via an interprocess communication or similar suitable port. Thus, while the profile service 210 executes in an untrusted or user-mode space, the code of the profile service 210 may be verified at execution to be signed by a trusted authority.
  • FIG. 3 is a more detailed view of the developer access profile 208. As noted above, developer access profile 208 may be a set of data stored in the memory of device 100, which indicates that the device may be permitted to execute software even though it has not been signed by trusted authority 102. Developer access profile 208 can include device identifier data 302, developer identifier data 304, and entitlement data 306.
  • Device identifier data 302 specifies one or more device identifiers 302 to, which the developer access profile 208 applies. In embodiments where the devices 100 are mobile telephone devices, device identifier data 302 may include an array of mobile telephone device serial numbers.
  • Device identifier data 302 for a developer access profile 208 may include one or more device identifiers 204 for different devices. In one embodiment device identifiers 204 may be specific identifiers, which may be represented as numeric or alphanumeric data, for specific devices. In other embodiments, more generalized device identifying data may be utilized. For example, some device vendors and/or manufacturers may provide devices having device identifiers, which are specific to an organization. For example, a device vendor and/or manufacturer may customize certain aspects of device identifiers 204 associated with devices based on the organization to, which they are delivered.
  • Device identifier data 302 may include ranges of device identifiers, rather than listing each individual device identifier value. In still other embodiments, a bit mask or wild card characters may be used to specify that the developer access profile applies to all devices having specified identifier characteristics. In still other embodiments, device identifier data 302 may specify that developer access profile 208 applies to all devices. For example, in one such embodiment, software signed by one or more of the developers identified in developer identifier data 302 may be authorized to run on any device 100 upon, which the developer access profile 208 may be installed.
  • As noted, developer access profile 208 may further include developer identifier data 304, which specifies software developers 104 to whom the developer access profile 208 applies. Developer identifier data 304 may take various forms. In some embodiments, developer identifier data 304 may be public keys associated with software developers 104 covered by the developer access profile 208. Other types of identifiers may also be used. In some embodiments, developer identifier data 304 may be stored in an array data structure stored within the developer access profile. Of course, any suitable data structures may be used.
  • Furthermore, developer access profile 208 may include entitlement data 306. Entitlement data 306 may include data, which indicates the types of operations that are allowed for the software modules 206 signed by developers identified in the developer identifier data 304 on the devices 100 specified in device identifier data 302. A particular developer access profile 208 may specify more than one developer 104 as being authorized to digitally sign code authorized by the developer access profile 208.
  • Entitlement data 306 may specify the types of access that are permitted for applications signed by the developers 104 identified in the developer identifier data 304 with respect to the devices 100 identified in device identifier data 302. The entitlement data 306 may take the form of key-value pairs. The values may include, for example, numeric, Boolean, or alphanumeric data. In one embodiment, the entitlement data 306 may include an array or other data structure of predefined Boolean variables, which are indicative of various specified entitlements.
  • In one embodiment, entitlement data 306 may include the capability to be executed. In one embodiment, a debug allowed entitlement may be included, that when set to “TRUE” in a particular profile indicates that code signed by developers 104 associated with developer access profile 208 are permitted to execute software modules 206 on device 100 in a debug mode. If the debug mode allowed entitlement may be set to “FALSE,” and developer 104 attempts to run the software in debug mode on device 100, policy service 210 may block the execution of the code. Other such entitlements may include entitlement data that may be indicative of a trace-allowed entitlement. Trace-allowed entitlement may allow software modules 206 digitally signed by developer 104 to be compiled and executed in trace mode on devices 100.
  • Other entitlements may control access to networking resources of device 100, data, libraries, or applications that have security or privacy implications such as address book data. In addition, other entitlements may control access to particular developer APIs including telephony, networking, address or phone storage, or multimedia APIs.
  • FIG. 4 is a block diagram illustrating illustrates relationships between events that occur when a request may be received and processed by the system between software components of one embodiment of computing device 100. As shown, in event 1, operating system 202, which can include a trusted space, may receive a request (in response to a user request to execute the particular software module 206 or in response to a request of another software component on device 100 to execute the particular software module 206) to executed an identified software module 206. In one embodiment, the request can include a reference to a directory or file of the storage 209, which stores the executable instruction code of software module 206.
  • In event 2, operating system 202 may communicate a request to authenticate software module 206 to policy service 210. In one embodiment, the authentication request can include the reference to the storage location in storage 209 associated with software module 206. Operating system 202 may also provide a digest of at least a portion of software module 206 to policy service 210. Alternatively, or in addition, policy service 210 may generate a digest of all or a portion of software module 206. In one embodiment, the digest may be based on digest values determined for each code page or each file associated with software module 206. In one embodiment, requests to policy service 210 may include other data such as specific entitlements that are to be enforced.
  • For example, operating system 202 may specify that the entitlement may be an entitlement to execute, to debug, or to access specified system resources. Operating system 202 or another portion of the operating system of device 100 may be configured to request entitlement authorization for access to specific networks such as a mobile telephone network, a Bluetooth stack, or to specific capabilities of device 100 such as to access a microphone, speaker, camera, or other I/O interface of device 100.
  • At event 5, policy service 210 may access one or more profiles 208 associated with execution of software module 206. In one embodiment, the profiles are accessed from storage 209. In one embodiment, profiles 208 include a particular profile associated with a developer of software module 206. It may be to be recognized that while profiles are described herein with respect to software developers 104 other than trusted authority 102, access to software modules provided by trusted authority 102, e.g., the device or operating system developer, may also be controlled using the systems and methods described herein.
  • At event 5, policy service 210 may verify the execution rights of software module 206 based on the digest and/or profile 208. For example, policy service 210 may be configured to receive a signature associated with the digest of software module 206 and cryptographically verify the digest. In one embodiment, policy service 210 may use a public key associated with a particular developer 104, and, which may be included as part of profile 208, to verify the signature of the digest.
  • In one embodiment, to ensure that the profile and the developer key may be trusted, policy service 210 cryptographically verifies that the profile may be trusted by trusted authority 102. In this embodiment, policy service 210 may verify the profile by verifying a digest or other signature of the profile (and its contents) using a public key of trusted authority 102 that may be stored on device 100 or otherwise accessed, e.g., via a data network, by device 100.
  • Policy service 210 may be further configured to verify that software module 206 may be authorized for the particular device 100. For example, in one embodiment, profile 208 can include one or more device identifiers or data for matching device identifiers (e.g., a mask or wildcard to match a specified group of devices 100).
  • Policy service 210 may compare the identifiers to an identifier securely maintained by device 100 and authorizes the software module when the identifier data of the policy 208 matches that of device 100. The device identifier may include any data stored on the device that may be used for identification including a manufacturer serial number, device or subscriber identifiers of a mobile telephone device such as an Integrated Circuit Card ID (ICCID), International Mobile Subscriber Identifier (IMSI) of a SIM card currently inserted into device 100, the International Mobile Equipment Identifier (IMEI) encoded on the device, an electronic serial number (ESN), or any other data suitable to identify the devices 100 for, which a particular software module 206 may be authorized.
  • Policy service 210 may be configured to authorize software module 206 based on further entitlements or other capabilities as specified by profiles 208. Executable or not-executable may be considered as an example of am entitlement. Other entitlements may specify whether the particular software module 206 may execute or access services based on one or more of profiles 208 and on any other policy that policy service 210 may be configured to enforce.
  • Policy service 210 may be configured to execute in user space such that the policies and profiles enforced therein may be arbitrarily complex and subject to update without increasing the size of the kernel or other protected memory spaces and be more easily developed and revised without the difficulties generally associated with kernel programming.
  • It is to be recognized that while FIG. 5 illustrates an example of operating system 202 determining whether a particular software module 206 has an entitlement to be executed, the methods and systems described herein may be used to authorize access to device hardware capabilities, other services of the kernel, other operating system services, or services of another software module 208. For example, device 100 may include a debugging or trace facility provided, for example, by operating system 202 or other operating system component that may be only authorized accordingly to policies enforced by the policy server 210. For example, a debugger interface (not shown) may request authorization for debugging of a particular software module 206 using the system illustrated in FIG. 5 based on a debugging entitlement specified in profile 208 associated with software module 206 or via other policy.
  • Entitlements may be enforced via one or more policies associated with the device. For example, a policy for enforcing entitlements may include processing entitlement data in profiles as a white list, e.g., software module 206 may be authenticated for a particular such entitlement when profile 208 can include data indicating that entitlement exists for the particular software module 206 and/or the particular device 100. Another policy may enforce entitlements based on a blacklist, e.g., software module 206 may be authenticated for a particular such entitlement unless profile 208 or applicable policy can include data negating that entitlement for the particular software module 206 and/or the particular device 100. In another embodiment, device 100 may be configured with a policy such that some entitlements may be configured to be enforced via a white list while others are configured to be enforced via a blacklist.
  • Other policies may be included to more finely control particular entitlements or to resolve conflicting profile data. For example, in one embodiment a mobile service provider may include a particular carrier profile 208 in devices for use on its network that further specifies entitlements to particular device capabilities, e.g., voice network or dialer access, which may conflict with the developer profile 208 for particular software modules 206. In such an event, a policy of device 100 may specify that the entitlement specification of one of the profiles controls.
  • In event 6, when policy service 210 may verify the entitlements and/or other execution rights of the software module 240, policy service 210 provides operating system 202 or other client of policy service 210 with data indicative of the entitlements of software module 206 and/or the entitlements for, which the request to authenticate was made. In event 7, operating system 202 may then execute software module 206 in accordance with the entitlement data received from policy service 210.
  • FIG. 5 is a flowchart illustrating on embodiment of a method 500 of verifying entitlements of software modules 206 in devices 100. The method may begin at a block 502 in, which a trusted space of operating system 202 receives a request to execute a particular software module 206. In one embodiment, the trusted space may be established on startup of the device by a bootloader of device 100 that cryptographically verifies operating system 202 prior to loading.
  • In block 504, the trusted space process communicates data indicative of software module 206 to policy service 210 executing in untrusted space, but to, which trust has been granted upon initial execution of policy service 210. The data may include a reference to a storage location of software module 206 and, optionally, data indicative of a particular entitlement being authenticated.
  • Next at block 506, policy service 210 authenticates software module 206. In one embodiment, policy service 210 authenticates software module 206 based on cryptographic authentication. For example, policy service 210 may authenticate software module 206 by verifying a digital signature of software module 206 using suitable cryptographic techniques such as asymmetric/public key encryption. Further, one or more entitlements associated with software module 206 may be authenticated similar cryptographic techniques. Further details of block 506 may be found with reference to FIG. 6.
  • Proceeding to block 508, policy service 210 communicates data indicative of execution rights of the software module to the kernel of operating system 202. The data may include a Boolean authentication response, data indicative of one or more entitlements of software module 206, a verified digest of software module 206, or any other suitable data relative to the request.
  • In block 510, operating system 202 or other trusted process may then execute software module 206 or may perform services for software module 206 based on the authenticated entitlements.
  • FIG. 6 is a flowchart illustrating block 506 of the method of FIG. 5 in more detail. At block 602, policy service 210 may calculate a digest of at least one file or other data structure associated with the executable code of software module 206. The digest may be calculated using any suitable hash algorithm, including, for example, SHA-1.
  • In block 604, policy service 210 may identify one or more profiles 208 associated with software module 206 and/or device 100. In one embodiment, profiles 208 can each include a signing key and data indicative of entitlements of software module 206. For example, an entitlement may include a data structure in tabular form such as illustrated in Table 1.
  • TABLE 1
    Example Profile Data
    Developer Signing Key 123555
    Device ID1 123FFF
    Device ID2 123FFF
    Executable TRUE
    Debuggable FALSE
    Can_Access_Network TRUE
    Code Digest AAFF1144BB
  • Software modules 206 may be associated with profiles 208 via key-value pairs of the profile that identify the digest (e.g., the “Code Digest” illustrated in Table 1) of software module 206. Profile 208 may further include a digital signature, e.g., a digest of the profile cryptographically signed by, for example, trusted authority 102. Next at a block 606, policy service 210 cryptographically verifies profile 208, e.g., by verifying that the cryptographic signature of the digest of profile 208 may be correct.
  • Moving to block 608, policy service 210 verifies that profile 208 may be applicable to the particular device 100. In one embodiment, the verifying may include comparing the device identifier 204 of the particular device 100 to the device identifiers listed in the signed profile 208. The previous signature verification at the block 606 may provide assurance that the device identified in profile 208 have not been changed or modified without authorization.
  • Next at block 610, policy service 210 may identify execution rights associated with software module 206 based on profile(s) 208. In one embodiment, the identifying can include accessing the entitlements of each profile.
  • In block 612, policy service 210 may verify that the entitlements to be verified for software module 206 are consistent with policies for computing device 100. In one embodiment, the verifying can include determining whether the requested entitlement may be included in profiles 208 associated with software module 206 and policies of device 100.
  • Proceeding to block 614, policy service 210 may then compare the digest value calculated at the block 602 to the signed digest of software module 206 and verify the cryptographic signature of the digest. It is to be recognized that depending on the embodiment, certain acts or events of any of the methods described herein can be performed in a different sequence, may be added, merged, or left out all together (e.g., not all described acts or events are necessary for the practice of the method). Moreover, in certain embodiments, acts or events may be performed concurrently, e.g., through multi-threaded processing, interrupt processing, or multiple processors, rather than sequentially.
  • FIG. 7 is a block diagram illustrating interaction of programs executing on the device 100. A first application, service, or other program 702 may receive requests for data or services from a second program such as one of the software modules 206. First program 702 identifies one or more entitlements associated with the service request and requests authentication of those entitlements for the second program from policy service 210. Policy service 210 can authenticate the entitlements of the second program based on one or more profiles including developer and/or carrier profiles. Based on the authenticated entitlements, first program 702 may then execute the requests.
  • For example, a key/password storage program may store various keys, passwords, or other private data for other programs and base access to data for a particular program on a corresponding entitlement. When a program requests data from the storage program, the storage program identifies one or more entitlements associated with the requesting program and requests authentication of those entitlements by policy service 210. The storage program may thus control access to various portions of its data according to the entitlements. Policy service 210 can provide a uniform way of controlling execution for other programs on the device 100 that incorporates policy control based on profiles such as those of developers and carriers.
  • FIG. 8 is a flowchart illustrating one embodiment of a method 800 of authenticating entitlements, for a first program executing on device 100 (e.g., first program 702 of FIG. 7) and entitlements of a second program executing on device 100. The method 800 may begin at a block 802 in which first program 700 executing on a processor of the device 100 receives a request to provide service or data subject to an entitlement from a second program, such as a particular executing software module 206.
  • In block 804, first program 702 communicates data indicative of the software module and may request that policy service 210 authenticate entitlements of the software module 206.
  • Next, processing may proceed to block 506, which was discussed above with reference to FIGS. 5 and 6. At block 808, policy service 210 may communicate data indicative of entitlements of the software module 206 to first program 702. At block 810, first program 702 may provide the requested service or data to the software module 206 based on the authenticated entitlements.
